After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
.

1 - NO particle filter regeneration.
2 - Write on the repair order: the parameter and status relating to the last failure:
– Mileage of last Particle filter warning light record
– Mileage of last Failed regeneration records
– Engine statuses for last Engine status records
Example: PR837 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3 - Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the warning light or Particle Filter message came on (appeared at the mileage of the last
Stored particle filter warning light) the customer did not follow the driving instructions: the failure which
occurred at the Mileage of the last failure was due to the engine being switched off.
4 - Service advisor explains to the customer the procedure to turn off the warning light, backed up by the
parameters written in the repair order: see PA R T D.
PA R T C
1 - Carry out a regeneration in the Renault dealership with the approval of the Techline.
Follow the procedure for command SC017 Particle filter regeneration.
Note: Do not carry out an engine oil change following an After-Sales regeneration.
2 - Explain the procedure for regeneration while driving to the customer to reduce returns to the garage:
see SECTION D:
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

SECTION D - Procedure for switching off the particle filter message or warning light on the instrument panel
Certain types of driving can trigger the activation of the particle filter warning light or message. This fault occurs
when the weight of soot is more than 30.8 g.
The customer must carry out a specific driving operation (cf. vehicle user manual) that consists of:
1. Making sure the engine is warm
2. Drive at a speed greater than 24 mph (40 km/h) for 2 minutes to initiate the regeneration process.
Initiating regeneration Minimum speed Minimum time
All vehicle types 24 mph (40 km/h) 2 minutes
3. Then drive at a speed of more than 24 mph (40 km/h) until the Particle Filter message or warning light on the
instrument panel goes out. In order for the procedure to succeed, it is necessary to drive without stopping
(without stopping the engine) or to leave the engine running at idle speed for an extended period of time. The
regeneration time depends on the vehicle and driving conditions but normally lasts about 20 minutes.
Regeneration duration Minimum speed Average time
All vehicle types 24 mph (40 km/h) 20 minutes
4. If regeneration when driving fails (the warning light has not switched off or the service warning light has come
on), carry out a particle filter regeneration in the Renault dealership. To carry out After-Sales regeneration:
check the oil level and remove some oil if the maximum level has been reached, then apply the procedure for
command SC017 Particle filter regeneration (see Interpretation of commands).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
